SPECIFICATION forming part of Letters Patent No. 751,747, dated February9, 1904.

Application filed March 25, 1903. Serial No. 149,517. (No model.)

To all whom, it Worry concern:

Be it known that I, HENRY O. NELsoN,a resident of Salem, in the countyof Oolumbiana and State of Ohio, have invented a new and usefulImprovement in Windows; and I do hereby declare the following to be afull, clear, and exact description thereof.

My invention relates to improvements in windows, transom-lights, and thelike, and more particularly relates to windows which both slide and alsorevolve, so that they are capable of being turned over for cleaning andother purposes.

The object of my invention is to provide simple and efficient meanswhereby the window or transom sashes are pivotally supported, so as tobe capable of being turned over for cleaning and other purposes, and atthe same time so mounting the same that the space between the sash andthe casing is effectually closed and by means which are simple inconstruction and not liable to get out of order.

To this end the invention consists of the usual casing and sash,together with weatherbars to which said sash is pivoted and which may ormay not be capable of sliding, and means whereby said weather-bars arepressed against the sash by the weight of the sash alone, thusdispensing with springs or other means which are liable to get out oforder.

The invention also comprises certain details of construction hereinafterdescribed and claimed.

In the accompanying drawings, Figure 1 is a front elevation, partly insection, of a double-sash window constructed according to my invention.Figs. 2 and 8 are vertical sections, on an enlarged scale, showing theprinciple of my invention. Fig. 4 is a horizontal section on the line 1I, Fig. 1. Fig. 5 is a front elevation, partly in section, showing theinvention applied to a transom-light; and Fig. 6 is a cross-sectionshowing a modified form of bar.

In the drawings my invention has been illustrated in connection withwindows and casings of sheet-metal construction which are fireproof; butthe invention is not limited thereto, as it can advantageously beapplied to ordinary wooden window and transom light constructions.

that the invention principally resides.

In the drawings the window-casing is shown at 1, and this may be of theusual or any desired construction and will be provided with the usualgrooves or channels 2, as is now common in all window constructions.

3 represents the window-sash. In order that the latter may revolve, itcannot fit into the grooves or channels 2 in the casing, but is merelyflush with the inner faces 4 of said casing.

In the channels 2 are sliclably mounted. the weather-bars 5, whichpreferably will be of trough form, as shown, having their open sidesfacing inwardly or toward the channels 2 and being provided with roundedouter faces which fit in depressions 6 in the sash 3. The latter areprovided with suitable pivots or trunnions 7, which project throughholes in the Weatherbars, so that said sashes may be turned over on saidtrunnions for cleaning and other purposes in the well-understood manner.In the weather-bars 6 are suitable bearings 8 to support the trunnions 7of the sash, these bearings preferably being small grooved. rollers, asshown, so as to form practically fricti0n less bearings for thetrunnions. The holes in the weather-bar through which the trunnions passare larger than .said trunnions, so that there is friction only wherethe trunnions touch the rollers.

Means must be provided for pressing the weather-bars against the sashes,so as to exclude air, and it is in the means for doing this Heretoforethis has been done by securing to the bars spring-pressed rollers whichbear against the casing and through the resiliency of the spring pressthe bars against the sash. Springs, however, are liable to varyconsiderably in strength and temper and also liable to become lame, sothat in practice it has been found that the bars will assume an inclinedinstead of a true vertical position.

According to my invention the Weatherbars are pressed against the sashby means which are controlled entirely by the weight of the sash itself.To this end the suspending means or cord 9 for the sash is connecteddirectly to the bars 5 near their lower ends and passes upwardly andover the usual sheaves and is provided with the usual weight 11.Interposed between this sash-cord and the bottom of the channel 2 in thecasing are suitable tension devices which are of greater width than thedistance between the bottom of the channel and the cords 9 when in astraight condition, so that said tensiondevices force the cords out ofline, and therefore produce a tension which has a tendency to force thebars against the sash. These tension devices are shown as swingingframes 12, which are mounted on pivots 13, secured to the bars, and havetheir free ends 14 interposed between the sash-cord and the channel inthe casing. Preferably the free end of the swinging frames will beprovided with antifriction-rollers 15, bearing against the casing, andsuitable studs orthe like, 16, which contact with the sashcord 9. Therewill also be provided in the weather-bars suitable studs or other means17, which, together with the pivots 13, serve as guides for the cord andwhich determine the position thereof. The pivots 13 of the swingingframes 12 serve as two of such guides.

The free ends of the swinging members 12 are always in contact with thecasing and are wider than the distance between the casing and the cordwhen straight, so that they press on the cord and through the latterpress the bars against the sash. The tendency of the said sash-cord tostraighten tends to force the rollers 15 against the casing; but as therollers are always in contact with the casing, and hence relativelystationary, the tension of the cords serves to press the bars firmlyagainst the edge of the sash. The degree of this pressure will dependentirely upon the weight of the sash and bars, or what is equivalentthereto, the weight of the window-weight.

In Fig. 5 I have shown the invention appliedto an ordinary transom-lightwhich has no sliding movement. In this case the sashcords9 are notconnected to a weight, as with the sliding windows, but their upper endsare connected to suitable studs 19, secured to the casing, so that thebars 5 and the sash connected thereto are suspended entirely from thesestuds, and as a consequence the tension of the cords will be directlyproportioned to thecombined weight of the sash and bars, and this willdetermine the pressure of the bars against the sash. As the sash in thiscase does not slide, the antifriction-rollers 15 are omitted.

In the drawings is shown a flexible metallic ribbon extending up as faras the upper ends of the weather-bars and there connected to the usualsash cord or chain; but it is obvious that the ordinary window cord orchain can be secured directly to the lower end of the weather-bars, ifdesired. By the term sashcord as used in the claims I intend to coverany suitable flexible suspending means, such as the ordinary cord usedor a chain or a flexible metallic ribbon or other means. The

weather-bar has been shown as practically trough or U shaped incross-section; but it is obvious that a tubular or semitubularWeatherbar, such as shown at 5 in Fig. 6, will serve my purpose just aswell. In case of the tubular bar it Will be necessary to provide on theinner side thereof suitable openings or slots 5", through which thetension devices can project. The U-shaped bar shown, however, is muchsimpler and preferable. Instead of the swinging tension device describedI may use any other means for securing the same result, such as a blockor roller mounted to move transversely of the bar.

It will be observed that there are no springs or similar means .in mydevice, but that all parts thereof are such as to need no attentionafter being put in place and cannot easily break or get out of order.Furthermore, the construction is such that uniform pressure will beapplied to both ends of the weatherbar, thus insuring the bar beingalways in a true vertical position and effectually closing the spacebetween the revolving sash andcasing. The arrangement also admits of theemployment of comparatively large rollers 15, hearing against thecasing, so that friction is largely reduced.

IVhat I claim as my invention, and desire to secure by Letters Patent,is-

1. The combination with a window-casing and inclosed sash, ofweather-bars interposed between said casing and sash and connected tothe latter, cords or the like attached to said bars for suspending thesash, and meansarranged to contact with the casing-and with said cordsand acting by the tension of the cords to press the bars against thesash.

2. The combination with a window-casing and inclosed sash, ofweather-bars interposed between said casing and connected to the latter,cords or the like attached directly to said bars and serving to suspendthe sash, andmeans actuated by the tension of said cords for pressingthe bars against the sash.

'3. The combination with a window-casing and inclosed sash, ofinterposed weather-bars to which the window is pivoted, cords secured tosaid bars for suspending the sash, and tension devices in said barsarranged to contact with the casing and with said cords, the arrangementbeing such that the straightening of the cords by the weight of the sashforces said devices against the casing and presses the bars against thesash.

4:. The combination with a window-casing and inclosed sash, ofinterposed weather-bars to which said sash is pivotally secured,suspending-cords or the like connected to said bars, guides over whichsaid cords pass, and means mounted in said bars so as to be movabletransversely thereof, said means being interposed between the cords andcasing and being of greater width than the distance between said guidesand the casing, whereby Lil the straightening of the cords forces saiddevices against the casing and presses the bars against the sash.

5. The combination with a window-casing and inclosed sash, of interposedweather-bars to which said sash is pivotally secured, suspending-cordsconnected to said bars, tension devices hinged to said bars and havingtheir free ends interposed between the cord and casing and being ofgreater width than the distance between the casing and the normalposition of the cords, whereby the straightening of the cords forcessaid devices against the casing and presses the bars against the sash.

6. The combination with a window-casing and inclosed sash, of interposedweather-bars to which said sash is pivotally secured, suspending-cordssecured to said bars, guides in said bars over which said cord passes,swinging tension devices hinged to the bars and having their free endsinterposed between the cords and casing and being of greater width thanthe distance between the cord-guides in the bars and the casin 7. Thecombination with a window-casing and inclosed sash, of interposedweather-bars to which said sash is pivotally connected, said bars beingtrough-shaped in cross-section, suspending-cords secured to saidweather-bars, guides in said bars over which said cords pass, andtension devices mounted in said bars so as to be movable transverselythereof, said devices being of greater width than the distance betweenthe cord-guides in the bars and the window-sash, whereby thestraightening of the cords forces said tension devices against thecasing and presses the bars against the sash.

8. The combination with a window-casing and inclosed sash, of interposedhollow weather-bars to which said sash is pivotally connected,bearing-blocks in said bars on which the sash-pivots rest,suspending-cords secured directly to said sash and means for pressingsaid bars against the sash.

9. The combination with a window-casing and inclosed sash, of interposedhollow weather-bars to which said sash is pivotally connected,bearing-rollers in said bars on which the sash-pivots rest,suspending-cords secured to said bars, and tension devices in said barsarranged to contact with the casing and with the cords, the arrangementbeing such that the straightening of the cords by the weight of the sashforces said devices against the casing and presses the bars against thesash.

In testimony whereof I, the said HENRY O. NELsoN, have hereunto set myhand.
